Open-source enterprise software company Red Hat has updated its flagship operating system, Red Hat Enterprise Linux (RHEL), to take full advantage of the latest spoils from the heated microprocessor battle between Advanced Micro Devices and Intel.

RHEL version 5.5, released Wednesday, has been reconfigured for Intel's just-released eight-core Nehalem-EX and

The software also supports the IBM eight-core Power7 processors, released in February.

"This is a great time for the next version of RHEL to hit the market," said Pund-IT analyst Charles King. This latest round in the continued proliferation of cores within AMD, IBM and Intel processors represents an "inflection point" for the industry, one that could spur a lot of data-center server consolidation, through the use, at least in part, of virtualization, he said.

To help customers harness all this concentrated horsepower, "There's a huge amount of work we've done for RHEL 5.5 for system scalability optimization," Burke said. Improvements have been made in the system scheduler, memory allocation and power management.

The scale of these processors could enable a much wider use of virtualization, Burke said. To this end, the new operating system has been reconfigured in such a way to better handle large virtualization loads. "The [processors] have a lot of new primitives that we exploit in the OS," Burke said. Such primitives "allow the guest instances to directly access their device drivers" instead of trafficking data through the hypervisor layer, he said.

Burke said that thanks to this direct access to drivers, a single virtual guest running on a RHEL server can saturate a 10 Gigabit Ethernet link. "The hypervisor doesn't have to be the middleman for all those operations," Burke said.

While some I/O-intensive applications, such as database servers, can experience as much as a 30 percent reduction in performance when virtualized, these new technologies could reduce that latency to as little as 5 percent, Burke contended.

RHEL's support for IBM's Power7 is significant as well, King said. For the past several years, IBM has been marketing Linux-based Power Systems as a lower-cost alternative to those systems running Sun Solaris or Hewlett-Packard HP-UX. RHEL's support of Power7 will help IBM continue this effort of purloining customers away from the Unix camp, King said.

Beyond support for the new round of multicore releases, RHEL 5.5 has a number of other new features as well. It has been updated to extend Active Directory integration, through the use of the latest version of Samba file- and print-sharing software. Also, for the first time, RHEL's version of SystemTap can trace the run-time performance of C++ applications (much like Oracle's DTrace does for Solaris' applications).

RHEL 5.5 also aggregates all the bug fixes and maintenance patches since the release of RHEL 5.4, released last September.

ARN Exchange: Channel discusses security spending priorities

Customers spending priorities, drawing up a security strategy for customers and partners, detailing how partners can increase profit through security and outlining key areas of market growth ahead were some of the topics discussed at the ARN Exchange event in Sydney. Partners got together to talk about the spending priorities of customers within the security market today and the skills required from partners to deliver those services. The event was in association with Juniper Networks, Webroot, Cloud Plus and Mimecast. Photos by Christine Wong.

What are the spending priorities of customers within the security market today and what are the skills required from partners to deliver those services? An overview of the security market in Australia was debated in the ARN Exchange event in Melbourne with discussions covering the customers spending priorities, drawing up a security strategy for customers and partners, detailing how partners can increase profit through security and outlining key areas of market growth ahead.

The channel came together for the forth running of the ARN Emerging Leaders Forum in Australia, created to provide a program that identifies, educates and showcases the upcoming talent of the ICT industry.
Hosted as a half day forum, attendees heard from industry specialists as keynoters and panellists discussed leadership paths and career choices. Hall of Fame members and industry mentors​ hosted small groups of future leaders to mentor and advise.
This also marked ARN's inaugural 30 Under 30 Tech Awards, which recognised young talent in the Australian IT industry across technical, sales, marketing, management, human resources and entrepreneur categories.
